Abstract

La présente invention se rapporte à un système de communication sans fil. Plus particulièrement, la présente invention se rapporte à un procédé et à un appareil permettant de transmettre un SRS dans un système à plusieurs antennes. Ledit procédé consiste : à obtenir des informations spécifiques servant à définir un premier groupe d'antennes et un second groupe d'antennes parmi une pluralité d'antennes, ce premier groupe d'antennes comportant une ou plusieurs antennes mises dans un état actif afin de réaliser une communication avec une station de base, et ce second groupe d'antennes comportant une ou plusieurs autres antennes mises dans un état inactif ; à transmettre un SRS à la station de base si une condition prédéterminée est remplie, à condition que le second groupe d'antennes soit mis dans un état inactif ; et à mettre le second groupe d'antennes dans un état inactif après la transmission du SRS.
